Background
The ventilation system of traditional central air conditioner usually adopts the filter screen board to carry out filtration to ventilation system's air supply, and when central air conditioner's ventilation system worked, the filter screen board was caught particles such as dust at first to carry out filtration to the air inlet. The captured dust is mostly collected on the windward side of the filter screen plate. As the running time of the air conditioning unit is accumulated, the filter screen plate starts to be blocked, the resistance to the air flow is gradually increased, the energy consumption is gradually increased, and when the resistance is increased to a certain critical value, the filter screen plate needs to be cleaned or replaced for maintenance. When the filter screen plate cannot effectively work, the filter screen plate needs to be cleaned or replaced manually in time, and from the economic aspect, the labor cost and the consumable replacement cost during maintenance are very expensive.
Taking tobacco processing as an example, along with the rapid development of modern tobacco agriculture, each tobacco leaf main production area successively establishes an industrial intensive bulk curing barn group. Because the intensive curing barn is built intensively, the curing barn capacity is increased, so that the oil-containing air generated in the curing process of tobacco is also increased, and the ventilation equipment such as a central air conditioner for the curing barn can cause the adhesion of oil stains and dust to a filter due to long-time ventilation, so that the blocking occurs, the resistance to air flow is gradually increased, the energy consumption is gradually increased, and the related equipment for self-cleaning of the central air is designed for reducing the labor intensity of manual cleaning by the person skilled in the art.
